It's free.

I use one dedicated free debit card to pay for all my subscriptions. You can see the bank statements in details every month. Also graphs.

In the US, you can even earn at least 2% cash back with a free credit card and get the same breakdown and analysis from almost any bank website.

I use virtual cards via privacy.com to pay for subscriptions. I generate a virtual card with a monthly or annual limit on it for each individual subscription service. Each card is backed by my real credit card. When a virtual card is charged, my credit card is charged. If it's charged over card limit, the transaction doesn't go through. The nice thing about this is i can login to my privacy.com account and look at all of my subscription spend. If I ever needed to cancel any subscription I can also burn the virtual card so I don't get over charged.

I use bobby [0] for that

I wouldn't.

Is this supposed to be a meta joke?

The major Canadian banks offer this as a standard feature.
